Gold Rush

Parker risks destroying Big Red to find Mud Mountain's big gold; Rick's forced to slow down his operation when massive rocks threaten to destroy Monster Red; Tony heads to the Yukon River for a quick cash infusion.

As gold prices soar, Parker considers buying new ground in Alaska; the Ness crew face disaster while transporting heavy loads to their new claim.

Parker hopes to reverse his cash flow by pivoting to a new cut while Rick's season lays in the hands of a green mechanic. Tony taps an old favourite spot and Fred finds riches in the wilderness.

Rick's crew race to rescue a greenhorn and her rock truck; in a rush to get on the gold, Parker's team send water flooding into their claim; Tony's team attempt a stone-age fix to keep his operation running.

Tony's confronted with news that throws him into a tailspin; Fred banks his first gold of the season; Parker's crew stall out at the Airstrip.

To fuel his big gamble, Parker cranks up Sluicifer; Fred faces a shutdown after a surprise inspection; on the hunt for new ground, Brennan sinks Rick's massive 475 bulldozer.
